Perfection of relaying security information concisely. Rated 5 out of 5 stars
Gives another layer of security information for your connection. Uses changing color of the button based on security level alerts the user quickly. Good options for improving cipher security which would require poring through a great deal of web documentation and manual tweaks to implement otherwise. It indicates just how secure the connection is for each website with much greater detail than any other method. Perfection!
Another good resource is SSLlabs by Qualys for information and website security certificate rating.
